Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation button adapter capable of pressing a push button serving as a switch for operating various devices by operating a lever.

[0002]

2. Description of the Related Art For example, as a welfare device for a person who has difficulty climbing up and down stairs, a chair that moves along the guide rails is provided on a guide rail provided along the slope of the stairs, and the user simply sits on the chair. There is a chair-type stair climbing device that allows the user to climb up and down stairs.

The operation buttons serving as switches for moving the chair type stair climbing device up and down can be broadly classified into two types, a push button type and a lever type.

In the latter lever type, since the lever protrudes outside the chair type stair climbing device, clothes or the like are hooked on the lever, and the hooking causes the device to be operated in a situation not intended by the user himself. It is preferable to adopt the former push button type for reasons such as the activation of the button.

[0005] The push-button operation of the chair-type stair-climbing device employs a push-and-hold system. This is because if the user feels any danger during lifting or stops intentionally, if the user immediately releases the push button,
Care is taken to stop the device.

[0006]

However, in the case of the push-button type, there is a problem that if the hand or the fingertip is incapable, the push-button cannot be pressed with force.

[0007] Further, in the chair type stair climbing device, for example, if the ascending / descending speed is 6 m / min and the traveling process from the first floor to the second floor is 12 m, the push button must be kept pressed for two minutes, and the hand and It is a very harsh condition for a person with a fingertip disability.

Accordingly, an object of the present invention is to make it possible to push a push button by operating a lever, without changing the specifications of a push button type device, and to make it possible for a person with a hand or fingertip to use a push button type. It is an object of the present invention to provide an operation button adapter that enables the operation of the device.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention swings a lever protruding out of the mounting member to a mounting member disposed above a push button for operating an apparatus. The lever is provided with a cam for pushing the push button by swinging.

In the operation push button of the present invention, two push buttons are provided side by side for opposing operations of the device, the mounting member is disposed above the two push buttons, and the lever is pushed. This lever is pivoted to a mounting member so as to swing in the direction in which the buttons are arranged in parallel, and this lever is used to push one push button by swinging to one side and to push the other push button by swinging to the other side. May be provided.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a chair of a chair-type stair climbing device as an example of a push button type device.
And a backrest 3, an armrest 4, a footrest, and the like. Although not shown, it is attached to a guide rail installed along the slope of the stairs via a lifting mechanism.

At the tip of the armrest 4 of the chair 1, operating push buttons 5, 5 serving as switches for raising and lowering the chair by operating a lifting mechanism.
And a switch 6 for turning the power on and off. The push buttons 5, 5 are composed of two for raising and lowering the chair 1, and are arranged side by side along the moving direction of the chair 1. An arrow indicating the moving direction is displayed.

FIGS. 2 to 4 show an operation button adapter 1 for pressing the push buttons 5 and 5 by lever operation.
1, an attachment member 12 attached to the tip of the armrest 4 so as to cover the push buttons 5, 5, a lever 13 swingably attached to the attachment member 12 so as to protrude upward, and a lever 13 A cam member 1 for pressing the push buttons 5, 5 by swinging of the lever 13.
4.

The mounting member 12 is formed so as to fit from the upper surface of the armrest 4 to both sides thereof in accordance with the shape of the tip of the armrest 4. Can be adopted. The mounting member 12 includes a portion located directly above the push buttons 5 and 5 when fixed to the armrest 4,
A long through hole 15 is provided in the direction in which the two push buttons 5 are arranged in parallel.

The lever 13 has a structure in which a spherical grip 17 is provided at an upper end of a shaft portion 16 and a cam member 14 is attached to a lower end. The cam member 14 fits into the through hole 15 from the lower end of the shaft portion 16. When the grip 17 is located on the mounting member 12, the push button 5 is pivotally supported on the mounting member 12 by a shaft 18 so as to be able to swing in the parallel direction.

The cam member 14 has two cams 19, 19 projecting downward in the swinging direction of the lever 13 when the lever 13 is in an upright position shown by a solid line in FIG. The bottom surfaces of the buttons 19 and 19 are parallel to the upper surfaces of the push buttons 5 and 5 at an appropriate distance, and one cam 19 is located directly above the one push button 5 and the other cam 19 is located immediately above the other push button 19. When the lever is tilted as shown by the one-dot chain line in FIG. 4, the cam 19 on the tilted side pushes the push button 5 located immediately below the cam.

The operation button adapter according to the present invention is constructed as described above. The operation button adapter 11 is attached to the armrest 4 of the chair in the push button type chair stair climbing device.
When the lever 13 is tilted in the direction in which the user wants to move while sitting on the chair 1 and going up and down the stairs, the push button 5 located immediately below the cam 19 on the inclined side can be pushed by the inclined cam 19. The lifting mechanism operates in accordance with the pushed push button 5, and the chair 1 moves along the guide rail.

The inclination of the lever 13 can be controlled by grasping the grip 17 with a hand or pushing the grip 17 with an arm or an elbow. Therefore, the push buttons 5, 5 are pushed through the lever 13. This makes it possible to push the push buttons 5 and 5 even if the hand or finger is not easy, and it is possible to keep pushing the push buttons 5 or 5 while the chair 1 is moving without difficulty. When the tilting operation of the lever 13 is released during the movement of the chair 1, the push button 5 or 5 whose pushing is released turns off the power supply to the elevating mechanism, and the chair 1 stops.

In the illustrated case, a chair-type stair climbing device is exemplified as a push-button device using the operation button adapter 11, but the push-button device is not limited to this. 11 can be dealt with by making the mounting member 12 a structure that matches the conditions of the device.

[0021]

As described above, according to the present invention, the lever is swingably attached to the mounting member disposed above the push button for operating the device, and the cam for pushing the push button by the swing is attached to this lever. The push button can be pushed by lever operation, and even people who have difficulty with their fingers or fingertips can easily push the push button for operation, and even such people can use push button type devices. Will be able to

Further, by simply attaching the operation button adapter to the push button type device, the push button operation can be performed without changing the specifications of the push button type device.
In addition, it is possible to freely press the push button directly and select the lever operation.
